You depend on measurements to make key decisions and discoveries. NI offers a wide range of data acquisition products, including the low-cost DAQ family for basic applications such as simple data logging, ...

This document is part of the Getting Started with NI-DAQmx Series. A Pulse Width Modulation (PWM) Signal is a technique for generating digital pulses to control an analog circuit. A PWM signal consists ...

I have multiple NI data acquisition (DAQ) devices. When I acquire data (DAQmx Read (VI) multiple channels) and then merge them in to one TDMS file by usingTDMS Write Function, the resulting file volume ...

I am scanning multiple channels using a multifunction DAQ device, but I am seeing the trends of one channel being reflected in the subsequent channel. However, when I only measure from a single channel ...

I want to control a stepper motor drive (step/direction) using the digital output on my USB DAQ and I have connected all the necessary wiring, so how do I control the motor for some simple moves in LabVIEW? ...

I have a data acquisition device that I would like to use on my Linux machine.Where can I find a list of DAQ hardware modules and devices supported by or compatible with NI-DAQmx Base?

I have a NI Multifunction I/O module with some Analog Output (AO) lines. I need to control an instrument using current. What is the current range the AO lines on my card?

I have a PCIe card, and it shows up in NI MAX and in Windows Device Manager, but it doesn't show up in NI Device Monitor. I have a USB RIO, and it shows up in NI MAX, but it doesn't show up in NI Device ...

When I am using NI-DAQmx with support for LabVIEW, is the Raw Data from the DAQmx Read.vi calibrated? How can I convert the acquired binary values to scaled values?

Why do I receive Error -200558 whenI try to use a task that contains multiple DAQ devices? One task cannot contain multiple independent devices. Create one task for each independent device.
